SPECIFICATION forming part of Letters Patent No. 711,983, dated. October 28, 1902. Application filed February 4, 1902. Serial No. 92,541. (No model.)

To LU whom, t 11m/y concern:

Be it known that I, FEANKWALLACE LEI- DECKER, a citizen ot the United States, re-

tating removal of the device from the boiler.

A further object is to present a gage-cock which shall combine simplicitv of construction, high eticiency and durability in use, and cheapness of production. v

X/Vith these and other objects in view, as will appear as the nature of the invention is better` understood, the same consists in the novel construction and combination of parts of a gage-cock, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like numerals of reference indicate corresponding parts, there is illustrated a form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to'shape, proportion, and exact manner of assemblage without departing from the scope of the invention, and in these drawings- Figure 1 is a View in sectional elevation of a gage-cock characterized by this invention, its normal or closed position being shown in full lines and its opened position indicated by dotted lines. Fig. 2 is a viewin top plan. Fig. 3 is a view in transverse section, taken on the line 3 3, Fig. 2, and looking in the direction of the arrow thereon. Fig. 4 isa perspective detached detail view of the valve or cut-off. Fig. 5 is a fragmentary detail view in side elevation.

Referring to the drawings, 1 designates a nipple having a threaded portion 2, to be screwed into the boiler and provided with a centrally-disposed passage-way 3, extending l throughout its length. The end of the nipple opposite its threaded portion is reduced .lar in cross-section, as shown.

transversely of its width to present a bearing 4, having straight side walls and arounded outer edge, as shown at 5, constituting a seat for the valve 6, the seat being provided with outward-projecting horizontally-alined lugs or bearings 7, preferably integral with theseat and to be engaged by the members of a yoke 8, the front end of which is provided with a threaded orifice to be engaged by the threaded end of a lever or handle 9, the' same being hollow throughout its length, whereby it will be prevented from becoming highly l1eated,and being preferably rectangu- The yoke 8 is a two-part structure, one member 10 of which is detachable and is held assembled with the other member by screws 11, and by thus constructing theyoke the same may be readily disconnected from the valve seat when desired.

The cut-off 6 is provided in its front face with a semicircular recess l2, adapted snugly to embrace the valve-seat, and with a passage-way 13, disposed at an angle to its width and normally out of register with the passageway 3 of the nipple, the cut-olf being normally held in this position by the weight of the lever 9. The rear end of the cut-off is provided with two extensions 14, whichV are adapted to overlap the upper and lower sides of the rear portion of the yoke, thus to hold the cut oft securely associated therewith. The valve-seat is provided with two stops or abutments 15 and 16, which are adapted to be engaged by the forward end portions 17 and 18 of the cut-ott, the stop 15 serving to limit the downward movement of the lever and the stop 17 its upward movement, as will be readily understood by reference to Fig. 1. The inner end of the lever 9 normally abuts against the rear face of the cut-0E, whereby to hold the same snugly against the valveseat, thus to prevent escape of steam or water through the gage, and as the cut-off Wears thisv may be taken up by screwing the handle inward, thus to force the cut-ott against its seat. In order to permit the yoke to be moved upward to the position shown in Fig. 1, the forward upper end portions of the yoke members are rounded, as shown at 19 in Figs. 1, 2, and 5.

When it is desired to ascertain the level of IOC the water in a boiler, the lever 9 is lifted to bring the passage 13 into register with the passage 3, whereupon the steam or water will be discharged through the passage 13 downward, whereby danger of scaldin g the attendant will be prevented, and as soon as the 1ever 9 is released it will drop, and thereby automatically cut olf the discharge from the boiler. y

It will be seen from the foregoing description that the gage-cock of this invention is exceedingly simple of construction and will by reason of the manner of its construction and assemblage be thoroughly efficient in 0peration. The only part of the device that will be liable to wear is the cut-off, and as this may .be adjusted in the manner pointed out to take up wear its use may be prolonged indefinitely. When worn out, however, it may readily be replaced at a small expense.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A gage-cock comprising a nipple provided with a valve-seat, and with a passageway, a cut-off adapted to be rotated on the said 'seat and having a passage-way normally out of register with that of the nipple, and

means for holding the cut-off in positive en- 4 gagement with the seat.

2. A gage-cock comprising a nipple provided with a passage-way and with a rounded valve-seat, a cut-off adapted snugly to fit the valve-seat and provided with a passageway, a yoke for holding thecut-OE in engagement with the seat, and meauscarried by the yoke for forcing the cut-oi against the seat.

3. A gage-cock comprising a nipple having a rounded valve-seat and a passage-way, a yoke pivotally connected with the valve-seat, a eut-'off carried by the yoke and engaging the seat and provided with a passage-way, and a lever adj ustably connected with the yoke and bearing against the cut-0E.

4:. A gage-cock comprising a nipple provided with a passage-way and having a rounded valve-seat provided with laterally-extending bearings, a yoke engaging the bearings and carrying a cut-off to work against the valve-seat and provided with a passage-way, and a lever adj ustably connected with the yoke to hold the cut-0E in engagement with the seat.

5. A gage-cock comprising a hollow nipple provided with a rounded valve-seat carrying laterally-extending bearings, a two-part yoke engaging the bearings, a cut-o carried by the yoke and engaging the valve-seat and provided with a passage-way, and a lever adjustably connected with the yoke to hold the cutoff in engagement with the seat.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
